Neither assert(0) nor assert(false) give any hint as to why control
getting to them is bad, and their more descriptive versions,
assert(0 && "description") and assert(false && "description"), jury
rig assert to add an error message when the utility function panic()
already does that directly with better formatting options.
This change replaces that flavor of call to assert with panic, except
in the actual code which processes the formatting that panic uses (to
avoid infinitely recurring error handling), and in some *.sm files
since I don't know what rules those have to follow and don't want to
accidentaly break them.

GpuTlbEntry was derived from a vanilla X86ISA::TlbEntry definition. It
wrapped the class and included an extra member "valid". This member was
intended to report on the validity of the entry, however it introduced
bugs when folks forgot to set field properly in the code. So, instead of
keeping the extra field which we might forget to set, we track validity by
using nullptr for invalid tlb entries (as the tlb entries are dynamically
allocated). This saves on the extra class definition and prevents bugs
creeping into the code since the checks are intrinsically tied into
accessing any of the X86ISA::TlbEntry members.
This changeset fixes the issues introduced by a8d030522, a4e722725, and
2a15bfd79.

Fixing an issue with regStats not calling the parent class method
for most SimObjects in Gem5. This causes issues if one adds new
stats in the base class (since they are never initialized properly!).
